TPM-25m optical power meter is widely used in the construc-
tion, maintenance, inspection and acceptance of optical fiber
communication network projects. The combination of fiber optic
power meter & light source, check continuity, and help evaluate
the transmission quality of optical fiber links. Smart appearance,
sustainable backlit display, and friendly operation interface make
you feel good about it. Provides 7 wavelengths detection, with
automatic wavelength memory function. The ultra-wide optical
power test range, precise test accuracy and new user self-cali-
bration function will make your work even better. Universal
interface design, support FC/SC/ST and other interfaces, without
complicated conversion. In addition, the LED lighting function
has been added to the product basis to allow it to be carried out
in a dark environment, further improvin.
Short press the power button to turn
on machine, and automatically start the
auto-off function, the default auto-off time
is 10 minutes. If you want to cancel this
function, press and hold the power button
.when starting up. When the power on icon
disappears, it means to cancel the auto-off
function.

Enter the optical power meter interface after
booting, short press the "REF" key to set the
current power value as the reference power,
which can realize relative optical power test
(insertion loss test) or absolute power test. After
entering the relative power test mode, the
insertion loss (dB) is displayed at the bottom of
the screen, and the screen displays the
reference value; short press the "dB" key to
switch between linear power and absolute
power display.
The units of linear power, absolute power, and
relative power are nW, dBm, and dB respectively.

On the optical power meter interface, short
press the "λ" key to switch the measurement
wavelength. You can choose 7 different test
wavelengths, 850nm/980nm/1300nm/
1310nm/1490nm/1550nm, 850nm, 1625nm.
To ensure the accuracy of thetest, the
selected wavelength must be consistent with
the wavelength of the measured optical signal
P absolute power = 10lgP linear power / 1mW.
P relative power = P absolute power-
P reference power.
